National Incident-based
Reporting System (NIBRS):

An incident-based reporting
system developed by the FBI for crimes known to the police.

For
each crime incident coming to the attention of law enforcement, a
variety of data is collected about the incident. These data include
the nature and types of specific offenses in the incident,
characteristics of the victim(s) and offender(s), types and value of
property stolen and recovered, and characteristics of persons arrested
in connection with a crime incident.
